Isolated bronchogenic cysts of the diaphragm are rare abnormalities. They are usually asymptomatic unless secondarily infected or large enough to cause compression of vital structures. The patient was a 31-year-old man and had no symptoms except mild postprandial epigastric discomfort. The chest X-ray and chest C-T examination revealed a mediastinal mass at the left cardio-vertebro-phrenic angle. We performed the operation under the impression of solid mass at mediastinum. We revealed that the mass was bronchogenic cyst in diaphragm. Therefore we report this case with review of literatures.

BACKGROUND: The CarboMedics prosthetic heart valve was produced in an attempt to improve the existing valve designs and was especially concerned with easily the implantation and further reduction of turbulence. Precise positioning of the valve in situ was achieved by the abilityof the valve to rotate relative to the sewing ring. Improved monitoring is possible due to increased radiopacity and the dacron sewing ring is coated with carbon to reduce pannus overgrowth. The leaflets have an opening angle of 78 degrees that apparently allows a rapid synchronous closure The aim of this study was to analyze the clinical performance of the CarboMedics valve prostheses(45 mitral 13 aortic and 7 double aortic-mitral valve replacement) were implanted in 65 patients(mean age 48.75+/-9.74 years) RESULT: The operative mortality was 3.1%(2/65) causes of death were low cardiac output syndrome. Total follow up was 1831 patient-months and mean follow up was 29.06+/-10.97 months/patient. No structural failure hemorrhage valve thrombosis and late death have been observed. Embolism occurred at a rate of 0.65%/Patient-year. Actuarial survival and thrombombolism free rate at 36 months were 96.9% and 98.4% respectively. CONCLUSIONS: The CarboMedics valve stands for low valve related complicatons.

BACKGROUND: Mitral valve replacement(MVR) with chordal preservation in patients with mitral vlavular disease has been proven to be beneficial for left ventricular function and for reduction of postoperative complication. MATERIAL AND METHOD: From January 1995 to July 1996, the early postoperative results of mitral valve replacement were compared between 20 patients who underwent chordae resection(classic MVR group) and 10 patients who underwent chordae preservation(preservation MVR group) in the Department of Thoracic and Cardiovascular Surgery, Chunbuk National University Hospital. RESULT: There was no significant difference between the two groups in age, sex, NYHA functional class, cardiothoracic ratio, echocardiographic finding, cardiopulmonary bypass time and aortic cross clamping time. The difference between preoperative and postoperative cardiothoracic ratio after 3 months was not statistically significant. At echocardiographic left ventricular evaluation, ejection fraction and fractional shortening decreased slightly in the preservation group then preoperative value (p=0.47, p=0.12), however, decreased significantly in the classic MVR group(p=0.03, p=0.04), and were statistically significant between the two groups(p=0.03, p=0.02). CONCLUSION: We conclude that MVR with chorda preservation seems to have a beneficial effect on postoperative left ventricular performance in mitral valve disease than the classic MVR.

Intramural esophageal dissection is a rare disorder that's characterized by a lengthy laceration between the mucosal and submucosal layers of the esophageal wall, and the esophageal wall is without perforation. The three different types of acute esophageal injury are a mucosal tear (Mallory-Weiss syndrome), full-thickness rupture (Boerhaave's syndrome) and intramural esophageal dissection. Most intramural esophageal dissections respond to conservative management with a very good prognosis. This rare condition should be considered in patients who present with acute chest pain, dysphagia or odynophagia, and particularly in the presence of a bleeding disorder or where there has been recent administration of antiplatelet medication, anticoagulants or thrombolytics to avoid inappropriate treatment with surgery. We present here a rare case of intramural dissection of the esophagus that occurred when the patient was taking antiplatelet medication.

Between January 1979 and August 1996, resection of a primary chest wall tumor was done in 51 patients. The mean age of the patients was 36.1 years (2 to 69 years). A palpable mass was the most common symptom (32 patients, 62.7%). The tumor was malignant in 11 patients (21.6%) and benign in 40 patients (78.4%). The tumors in 32 patients (62.7%) had developed from the bony or the cartilaginous wall and in 19 patients (37.3%) from soft tissue. Thirty seven of the patients with benign tumors were treated by excision (three of the patients: wide resection and reconstruction) without recurrence or death, and they are currently free from disease. Most malignancies (8 patients) were treated by wide resection and chest wall reconstruction. Five of them are currently alive. The chest wall reconstruction with Marlex mesh, Prolene mesh, or Teflon felt was done in five of the patients with malignant tumors.

To make an accurate diagnosis of esophageal rupture during balloon dilatation without the help of esophagograph, an infusion pump, a pressure transducer and a radiopaque esophageal balloon were connected through a three-way connector. The pressure transducer was connected consecutively to an amplifier, a differentiator and a speaker to detect a pressure drop in the esophageal balloon. Under fluoroscopic monitoring, a radiopaque balloon catheter was inserted in the mid-thoracic esophagus of 30 rabbits and inflated with air until the esophagus was ruptured. A pressure drop in the balloon at the time of esophageal rupture was not only recorded graphically, but also was identified through a speaker. To examine esophageal rupture grossly, the rabbits were sacrificed after esophagography. We could detect the time of esophageal rupture during balloon dilatation in all rabbits accurately by observing the pressure drop on the pressure recorder and by hearing the sound made on a speaker. In 8 patients with esophageal stricture, a deflated radiopaque balloon catheter was inserted to the position inside the narrowing point and inflated by injecting air until the 'hourglass' deformity created by the stricture disappeared from the balloon contour which the pressure change in the balloon was monitored with a pressure recorder. The balloon pressures at the time of disappearance of the "hourglass" deformity from the balloon contour ranged from 200 mmHg to 2000 mmHg in 8 patients with esophageal strictures. Esophageal ruptured did not occur in these patients. In conclusion, our results indicate that this new method is not only safe but promising for patients in the future with esophageal strictures. First, it would reduce the chance of mediastinitis in patients of esophageal rupture. Second, esophageal balloon dilatation can be performed more effectively and safely. Third, it is cost-effective. Forth, radiation esposure to the patient can be reduced.
